3-Point or Semi-Mount With Rear Axle
The following instructions are for leveling and cutting
height adjustments for 3-point or Semi-Mount cutters with
rear axles. There are three primary adjustments that
should be made prior to actual field operations:
• Level Left To Right
• Cutting Height Adjustment
• Level Front To Back
Proper adjustment of each of these items will provide
higher efficiency, improved cutting performance and
longer blade life.
WARNING
!
To avoid serious injury or death:
Always shut tractor down using “Tractor Shutdown
Procedure” provided in this manual before dismounting
tractor.
Level Left To Right
This adjustment should be made with cutter hooked to
the tractor that will be used for field operations
1. Having completed “Tractor Hook-up”, locate tractor
and cutter on a flat, level surface.
2. Use tractor’s hydraulic 3-point control to lower the
cutter until the front of the skid shoes are 2 to 3
inches off the ground.
Refer to Figure 3-6:
3. Place a spirit level or other suitable leveling device
across the front of the deck.
4. Adjust either one or both of the tractor’s lower lift
arms up or down to level the deck from left to right.
Some tractors have only a single adjusting crank.

WARNING
!
To avoid serious injury or death:
Avoid direct contact with cutter blades by wearing a pair of
gloves. Cutter blades have sharp edges and burrs that can
cause injuries.
1. With gloves on, carefully rotate blade tips on one side
of the cutter to the position shown in Figure 3-7.
2. Measure distance from end of blade (cutting tip) to
ground. This distance is the cutting height.
3. Using tractor’s 3-point hydraulic control lever, raise or
lower the 3-point arms until the front blade tip is at the
desired cutting height.
4. Set tractor’s 3-point hydraulic control stop once the
tailwheel and 3-point arms are properly adjusted.

Spirit Level
IMPORTANT: The front blade tip should be lower
than rear blade tip by approximately 1". The cutter is
subject to continuous material flow under the deck if
the rear blade is at the same height or lower than the
front blade causing horsepower loss, grass clumps,
blade wear, and frequent blade sharpening.
